CUSTOM CRM DEVELOPMENT SERVICES
No matter what you're building, we can help.
Our CRM development services cover custom CRM software development, cloud-based CRM solutions, mobile CRM applications, API integrations, and data migration. We support teams from discovery and architecture through deployment and ongoing optimization.
Custom CRM Software Development
Off-the-shelf CRM platforms force businesses to adapt workflows around rigid feature sets and licensing models that don't scale with growth. We build custom CRM solutions tailored to your sales cycles, customer data requirements, and business processes.
The architecture starts with your sales process and data model, not a template. We map customer touchpoints, define access levels based on actual team roles, and connect to ERPs and marketing tools where data needs to flow. So you get software that fits your operations without workarounds.
CRM Integration & API Development
Disconnected systems trap customer data in silos and require manual data entry across platforms. We build API integrations that connect your CRM with marketing tools, e-commerce platforms, support systems, and third-party data sources.
Integration work begins with mapping where customer data lives and where it needs to go. We connect Salesforce, HubSpot, Dynamics, or custom databases and handle the difficult parts—authentication, rate limits, error recovery, transformation logic—so records stay consistent without manual intervention.
Cloud-Based CRM Development
On-premises CRM systems limit remote access, complicate backup procedures, and require ongoing infrastructure maintenance. We build cloud-based CRM solutions on AWS, Azure, or Google Cloud that provide anywhere access, automatic scaling, and managed security.
Migration starts with your existing data and infrastructure constraints. We design the cloud architecture, move records without downtime, and configure security controls for your compliance requirements. You get a cloud CRM without inheriting infrastructure management overhead.
CRM Mobile App Development
Sales and support teams lose productivity when CRM access requires returning to a desktop. We develop native and cross-platform mobile CRM applications that provide full functionality on iOS and Android devices.
We optimize API payloads to ensure the interface remains responsive on cellular networks. We also implement push notifications to drive real-time action on urgent workflows. So apps work offline and sync when connectivity returns, with push notifications ensuring urgent leads don't wait.
CRM Data Migration & Consolidation
Migrating customer data from legacy systems or consolidating multiple databases risks data loss, duplicate records, and extended downtime. We manage CRM data migration projects that preserve data integrity while minimizing business disruption.
Every migration starts with understanding what could go wrong. We map source and target schemas, identify records that won't transfer cleanly, and build validation checkpoints throughout the process. Using phased cutovers with rollback capability let business operations continue even if issues surface during migration.
CRM Customization & Configuration
Standard CRM platforms provide generic features that don't match specialized industry workflows or unique business models. We customize Salesforce, Microsoft Dynamics, HubSpot, and other platforms to fit exact requirements.
Customization goes beyond adding fields. We redesign page layouts around how your team actually works, build automation rules that enforce your business logic, and create reports that answer the questions leadership actually asks. The platform starts behaving like software built specifically for your company, with data integrity and reporting you can trust.
CRM Performance Optimization
Slow CRM systems frustrate users, reduce adoption, and waste productive time. We optimize CRM performance by profiling database queries, refactoring inefficient code, and implementing caching strategies.
Diagnosis comes first. We instrument the system to identify where time goes—slow queries, inefficient API calls, bloated page loads. Our fixes target root causes rather than symptoms. Most clients see response times drop significantly within weeks, which directly improves user adoption and data quality.
CRM Security & Compliance Implementation
CRM systems storing customer data face regulatory requirements and security threats that standard configurations don't address. We implement security controls and compliance frameworks for GDPR, HIPAA, PCI-DSS, and industry-specific regulations.
Compliance isn't a checkbox exercise. We configure encryption, establish audit trails, define retention policies, and implement access controls based on what regulators actually examine. When audits happen, documentation is organized and systems demonstrate compliant controls without last-minute scrambling.

CRM DEVELOPMENT PROCESS
How we deliver CRM solutions that drive business value:
We've refined our custom CRM development services across dozens of complex projects since 2009. Whether you need end-to-end execution or support for your in-house team, we can step in wherever you need us to move projects forward without friction.
Discovery & Requirements Analysis
We work closely with stakeholders to understand business processes and CRM objectives. This includes mapping current workflows, identifying pain points, documenting data sources, and defining success metrics.
CRM Strategy & Platform Selection
We evaluate build-versus-buy decisions, assess platform capabilities, and recommend CRM solutions. This ensures the selected approach supports both immediate needs and long-term growth.
Data Architecture & Schema Design
We design database schemas that model customer relationships, business entities, and workflow requirements. We define object hierarchies, establish data validation rules, and map relationships.
UX Design & Prototyping
We create wireframes and prototypes that validate workflows before development begins. This reduces rework by surfacing usability issues and ensuring the CRM interface matches how teams work.
Custom Development & Configuration
We build custom CRM features, configure settings, and develop integrations using APIs and middleware. Development follows modular architecture principles to support maintainability.
Integration & Data Migration
We connect the CRM with existing systems like ERP platforms, marketing automation tools, and support systems. Data migration includes cleansing legacy data and validating accuracy.
Security & Access Control
We configure role-based permissions, implement data encryption, and establish audit logging. This protects data while ensuring teams have access based on responsibilities and compliance requirements.
User Acceptance Testing & Training
We conduct UAT sessions with actual users to validate functionality against requirements. This includes system navigation, workflows, reporting capabilities, and best practices to drive adoption.
Deployment & Change Management
We execute phased rollouts using pilot groups before full deployment, minimizing risk and gathering feedback. Change management includes communication, support, and adoption tracking.
Performance Monitoring & Optimization
We implement monitoring for system performance, user adoption metrics, and data quality. Post-launch optimization addresses bottlenecks and tunes queries to maintain responsiveness.
Ongoing Support & Enhancement
We provide production support, including bug fixes, user assistance, security patches, and feature enhancements. Regular health checks and planning ensure the CRM continues delivering value as needs evolve.

What tech leaders ask about our CRM development services:
How quickly can you staff a CRM development team?
We typically onboard CRM teams within 2–4 weeks. Our 4,000+ engineer bench includes CRM developers with experience in Salesforce, Microsoft Dynamics, custom development, API integrations, and data migration. This means we can assemble the right team quickly.
What level of experience do your CRM developers bring?
We screen over 2 million applicants annually and hire less than 1%. We only select senior engineers with 8+ years of proven experience. Our engineers have built custom CRM platforms, integrated CRM systems with complex enterprise architectures, and migrated legacy data without downtime. Our experts understand the trade-offs between custom development and platform configuration.
Will your team work in our time zone and integrate with our processes?
Yes. Our nearshore CRM developers work US business hours, communicate in English, and participate fully in your standups, sprint planning, and reviews. We adopt your tools, follow your processes, and operate as an extension of your in-house team.
Can you work with our existing CRM platform or legacy system?
Absolutely. Our engineers have worked with Salesforce, Microsoft Dynamics 365, HubSpot, Zoho, SugarCRM, custom-built CRMs, and legacy systems. We audit existing implementations, identify technical debt and integration gaps, and propose incremental improvements that don't disrupt ongoing operations.
Do you have experience in regulated industries?
Yes. We’ve delivered hundreds of projects for organizations operating in highly regulated industries and are ISO 27001 certified. That experience directly informs how we design and implement CRM solutions. We build with regulatory constraints in mind from day one, including strict data governance, access controls, and security controls. Our CRM work commonly incorporates encrypted data storage, audit logging, role-based access controls, and secure API design to support compliance with frameworks such as HIPAA, GDPR, and PCI-DSS.
How does BairesDev deliver CRM projects faster than in-house hiring or other vendors?
Three factors accelerate delivery. First, our 4,000+ engineer bench means we staff teams in 2–4 weeks instead of months of recruiting. Second, our CRM developers average 8–10+ years of experience, so they ramp up on your codebase and business logic quickly. Third, nearshore time zone alignment eliminates the 24-hour feedback delays that slow offshore engagements.
What factors affect the cost of a CRM development project?
Cost varies based on project complexity, team composition, and engagement duration. Custom-built CRM platforms require more investment than platform customization work on Salesforce or Dynamics. Integration scope and data migration complexity also influence total investment. Connecting two systems costs less than orchestrating data flows across ERP, marketing automation, and support platforms. Working with vetted senior engineers typically accelerates delivery and reduces rework, both of which often lower total project cost.
How do you maintain team stability over long engagements?
Our model is built for continuity and long-term partnerships. Most engineers stay on CRM projects for 2+ years, so you won't be dealing with constant churn. Our 96% client retention rate reflects organizations continuing to work with us year after year. When team adjustments are needed, our 4,000+ bench of vetted engineers allows quick scaling while maintaining momentum through documentation and structured handoffs.
What's the difference between staff augmentation and dedicated teams for CRM projects?
Staff augmentation embeds individual CRM developers into your existing team structure. You still manage priorities, sprints, and delivery directly. Dedicated teams operate as a self-managed unit, owning a defined scope or product area. We also offer end-to-end outsourcing where we handle end-to-end execution against requirements. During discovery, we help you identify which model fits your timeline, internal capacity, and project complexity.
Do you handle contracts and billing in the US?
Yes. We operate from US headquarters under US law and jurisdiction. All contracts and billing flow through domestic channels, making procurement straightforward.
